M14/fesses z It fi transparent plate-holde.' T rotated in the Vframe 4f. by means of a gear 10 mounted in the frame 4 and rotated by means of a thumb-nut 11, which gear engages teeth fori'ned on the peripher)v of the transparent plate-holder 7.

Formed on eaeh frame -1 is a horizontally disposed hracket 12 which is graduated on its outer face in inches and fraetions thereof, or in other system of linear nieasurement7 to indicate distances from the vertical diameter of the transparent plate 9, which corresponds to the center of the carriage 2-2 represented by the pointer b. Mount ed on the brackets 12 are slidable blocks 13 which are adapted to be moved to and fro on the brackets 12 by means of threaded shafts 14, which shafts are mounted 0n the brackets 1Q and are screw-connected to the bloek 13, as shown in Fig. 2. By turning a thumb-nut d on a shaft 14 the block 13 thereon will be caused to travel and assume any desired position on the bracket 12.

Pivotally mounted on the. block 13 is a pivoted bearing lfi which supports a horizontally disposed shaft, 1G, which shaft has a thumb-nut 1T on its outer end and is threaded on its inner end. This end extends some distance beyond the bearing 15 and enters an internally threaded tube 18 en the outer end of which is formed an ear enA gaging hook 1U.

Rigidly mounted on one lside of the bearing 15 and extending parallel with the sh:t ft lt and tube 18 is a tlat plate it), which plate is graduated in inches, or other system of linear measures, on its outer face and passes through bands or straps 21 on the'tube 18. The connection between the tube 1S and the plate *itl is, such as to prevent the tube 18 being rotated when the shaft 1G is rerolved7 but will cause it. to travel hack and forth on the shaft lti. The pivotal mounting,r of the hearing 15 admits of the ,shaft lo and the tube 1S thereon being folded against the back ot' the transparent platea-arming frame l, when the device is not in use` so as not to take up much space.

Mounted on the fact of the plate is a revolnlilc shaft ".22 provided with a thum'o piece e on its outer end and a beveled gear f on its inner end; the gear f meshingwith a gear kr/ which is screwed on a tlircadod stem .Y'l. 'l`he .stent if@ is' supported in a liearine' 'JT and is n'evcnted from rotatine' e l h thereon by means of a kry ot feather f'.' on the, bearingr whirh engages a longitudinal groove in the dem Bil, 'l`he gear f/ is held against longitudinal movement on tht` stem LIl h v means of a v\olte formed on the licaring," lt will be seen tha h v rotatingA the .shaft trl. the stein 21 will lic caused to travel hack and forth in the bearing i' to advance or retract a nosc rest 2H which is nxt v mounted on a cross head fl foimed on the lower end of the stem Q3. The man ing' .27 is pivotall) .mounted on tht fai)` of the plate so that the dircriior in which the stent extends may he :id inlted at va rious angles. the pirotal imitatingv oi the bearing; 2T eorrespondii ,g to the axis of the shaft 2Q; the asis of the stem il eorrespondin;l to the center .fi of the plate The adjustin-ent' of the bearing 2T is accomplished by means ot' a thumlrserew B() which is threaded in a bracket on the plate A. and is connected to the bearing;r 2T by means of a hall and socket. joint in such manner that by screwing the thumb-screw 30 the bearing 2i' will he rocked on its pivot into any desired position and securely retained therein.

The transparent plate il is provided with peculiar markings to adapt it to the particuA lar uses to which it put; the markirgrs being clearly illustrated in the enlarged view thereof, shown in Fig. t), and which consist of a horizontal and a vertical line j and c respectively, which cro` eaeh other at the center l of the transpart'fnt plate, These lines are given a prominent color. such as red. Intermediate of the lines and t: are, a series of radiatingr lines m which indicate degrees of deviation and are. colored green to form a Contrast. with the lines j and a", the purpose of the radiating lines7 m, being to enable the operator to determine the degree or angle of deviation of the pupil of the eye in relation to the horizontal and vertital lines. and /f re pectively. This done, by adjustiim` one transparent plate holder` i'. so that thi` center. will register with tht` pupil of thc ove therehehiml, and then settingr the oth i" tran--ioircnt phtte holder in a correspondine po-ition in rela tion to the center. v/l t t: he platt, ,li7 with the horizontal litt-s, and /s on the two plates, tl, on the .saine piane. itv dw ation ofthe pupil of tht` clic behind il .second plate. tl. can lie ther. rcridiljvy determinld and the de free of de\iation noted. series of contettttii' t'itthys /i colored Whitt'` are ranged on the lens with the point o' ini section 7 of the line` Vi 'l and ai a i t'tltttt'. lfr tlttct'tllto lit \i/i .if tir" :t state of dilation or coittiactitnt,
